BUTTON.

Specification of Letters Patent Application filed April 5. 1907. SerialNo. 866.542.

Patented Dec. 10, 1 967.

To all whom it may concern:

Be it known that we, JAMES C. DORAN and JAMES A. DORAN, both citizens ofthe United States, and both residing at Providence, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Buttons, of which the following is aspecification, reference being had therein to the accompanying drawing.

Our invention relates to garment buttons wherein the back plate andshank is shaped up from a single piece of metal, flattened and pierced.

In making a structure of the character above identified it has beenfound that the expense incurred by breakage of tools, cost of stock, andotherwise, has been excessive, and that the thinness of the pressedshank cut the engaging threads upon military and other buttons subjectedto heavy wear.

The essential object of this invention is to overcome the enumerateddisadvantages, and consists broadly in introducing into the shank anauxiliary member.

In the drawings which form a part of this specification Figures 1 and 2are bottom and transverse sectional elevations of a blank after thecupping operation. Fig. 3, a section on line as m of Fig. 1 after thewalls of the shank have been pierced and closed upon a ring. Fig. 4, aslde elevation of the same.

Fig. 5, a section on line y y of Fig. 1 after the insertion and closingin of the ring. Fig. 6, a similar section of the same when a disk isused. Fig. 7, a detail view of a ring. Fig. 8, a similar view of a disk,and Fig. 9, a perspective view of the back plate embodying my inventionengaged with a button front.

Like reference characters indicate like parts throughout the views.

To construct the novel button back the center of a blank, A, of thinmetal is bent by suitable tools to form a cup, B, oblong in crosssection, havin its broad walls, I), b, slightly tapering. nto the cup,B, is dropped a ring, C, and'the walls, I), are then by suitable toolssqueezed tightly against the sides of the ring. The walls are thenpierced forming a hole of a little less diameter than the diameter ofthe opening in the ring, and

the margins of the pierced walls inwardly bent around the ring as at 7),thereby oompleting the eye of thread opening, D. While we prefer to usethe ring, (3, as the auxiliary member satisfactory results are obtainedby using in its place a disk C. The disk is drop ed into the cup, B, andthe walls, 6, of the atter compressed against its opposite faces. Then atool pierces the walls, I), and the disk, 0, thereby forming the eye, D,as shown in Fig. 6. of using the disk'member is that three Walls arepresented to the action .of the piercing tool, whereby the latter isquickly du led and often broken.

The structure made as described produces a back plate, A, and integralshank B, whose eye, D, is of sufficient breadthto furnish a broadbearing surface to the engaging threads. The use of the auxiliary memberpermits the use of very thin metal blanks, which are sufficiently strongto answer the demands of the back plates, without making the shanks sothin as to endanger the engaging threads.

What we claim is,

1. A button back comprising a back plate, a hollow shank integral withthe back plate and an annular member fixed within the hollow shank.

2. A button back comprising a back plate, a hollow shank integral withthe back plate and provided with transverse perforations, and an annularmember fixed within the hollow shank with its open portion concentricwith the perforations.

3. A button back comprisin a back plate, a hollow shank integral with te back plate and provided with transverse perforations, and an auxiliarymember provided with an opening fixed-within the hollow shank and havingits opening concentric with the perforations.

A practical disadvantage In testimony whereof we have afiixed our
